Randomized Comparison of Continuous and Intermittent Heparin Infusion During Catheter Ablation of Atrial Fibrillation

Randomized Comparison of Continuous and Intermittent Heparin Infusion During Catheter Ablation of Atrial Fibrillation

Optimal anticoagulation using heparin with close attention to maintain therapeutic dosing during the procedure is important.

Randomized comparison of continuous and intermittent heparin infusion during catheter ablation of Atrial Fibrillation.

Intravenous heparin was used during the procedure to prevent catheter-induced thrombosis.

heparin is administered during the procedure to achieve recommended activation clotting times (ACT) values, typically >300 seconds to prevent thromboemboli during the procedure.

Most of the practitioners was that ACT level should be checked at 30- to 60-minute intervals and then have injected intermittently.

intermittent heparin infusion, concentration is great changed because the heparin has 30minutes half-period.

researchers postulate that a constant therapeutic concentrations would be beneficial to continuous infusion than intermittent infusion.
